Tutor

A tutor is an instructor who gives private lessons. Shadow education is a name for private supplementary tutoring that is offered outside the mainstream education system.

Normally, a tutor will help a student who is struggling in a subject of some sort. Also, a tutor may be provided for a student who wants to learn at home.

In the United States, the term "tutor" is generally associated with one who gives professional instruction (sometimes within a school setting but often independently) in a given topic or field.

British and Irish secondary schools

In English and Irishsecondary schools, form tutors are given the responsibilities of a form or class of students in a particular year group (up to 30 students). They usually work in year teams headed by a year leader, year head, or guidance teacher.

Form tutors will provide parents with most of the information about their child's progress and any problems they might be experiencing. Ordinarily, the form tutor is the person who contacts a parent if there is a problem at school; however, the year leader or guidance teacher may contact the parents, since the form tutor has full-time responsibility as a specialist subject teacher.

Tutor (officer)

In the University of Cambridge and University of Dublin a Tutor is an officer of a college responsible for the pastoral care of a number of students in cognate disciplines; as against a Director of Studies in Cambridge who is responsible for the academic progress of a group of students in their own discipline, with both Tutors and Directors of Study answering to a Senior Tutor. In the University of Oxford, the colleges fuse pastoral and academic care into the single office of Fellow and Tutor, also known as a CUF Lecturer.

Hockey helmet

Construction

Hockey helmets grip the head from inside by cupping the back of head, or the occipital protuberance. Helmet manufacturers will have a chart that relates their helmet sizes to head measurements.

Most helmets have tool-free adjustments, but on older models, the helmet size is adjusted by loosening the screws on the side to slide the front portion forward or back.

The shell of a hockey helmet is generally made of a substance called vinyl nitrile that disperses force from the point of contact, while the liner may be made of either vinyl nitrile foam, expanded polypropylene foam, or other material to absorb the energy, to reduce the chances of concussion.

Visor (armor)

A visor was used in conjunction with some Medieval war helmets such as the bascinet. The visor usually consisted of a hinged piece of steel that contained openings for breathing ("breaths") and vision. Visors protected the face during battle. Most knights or warriors who wore visors usually were spotted on horses during war, and more specifically in tournaments. The word beaver is sometimes used interchangeably with visor, as in Shakespeare's Hamlet, when Hamlet and Horatio are discussing the Ghost. Hamlet says: "Then saw you not his face?" to which Horatio responds "O yes, my lord. He wore his beaver up [i.e., his visor raised]".
